Revert pass-through of global install flags into generated hook scripts by j178 · Pull Request #1966 · j178/prek · GitHub

Closes #1965

Reverts #1753.

I agree that passing global flags down into installed scripts is not a good idea, so this reverts that behavior. We can add dedicated install flags later if we want explicit inherit behavior.

…ll into generated hook scripts (#1753)" This reverts commit 8501ccb.

Pull request overview

Reverts the behavior where prek install propagated global flags (e.g., -q/-v/--no-progress) into the generated Git hook scripts, aligning CLI semantics with user expectations and issue #1965. The PR also removes support for using absolute executable paths as language_version requests for several languages.

Changes:

Stop embedding global CLI flags into generated hook scripts (and simplify install/init-template-dir wiring).
Remove absolute-path language_version request support for Bun/Go/Node/Python/Ruby (docs + parsing/matching updates, tests adjusted).
Update integration tests/snapshots and language version matching APIs accordingly.

 #[test]
 fn install_with_git_dir() {
    let context = TestContext::new();


The removed install_with_quiet_flag / install_with_silent_flag / install_with_verbose_flag / install_with_no_progress_flag tests previously ensured global flags were not baked into the generated hook script. Since the default install snapshot won’t catch regressions that only happen when prek install is invoked with -q/-v/--no-progress, consider reintroducing at least one targeted test that runs install -q (or similar) and asserts the installed script does not contain those flags.

Bump hook script version after changing shim template

The generated hook command was changed here to remove inherited global flags, but CUR_SCRIPT_VERSION remains 4, and hook_impl only warns about outdated shims when the script version changes. That means repos that already have hooks installed from the previous template (also stamped as version 4, with -q/-v/--no-progress embedded) will keep the old behavior with no reinstall warning, so this revert does not actually take effect for existing installs unless users manually rerun prek install.

Useful? React with 👍 / 👎.

Most users should not need to change anything. - Generated hook scripts no longer preserve `-q`, `-v`, or `--no-progress` passed to `prek install`. This only affects users who expected those global flags to be baked into installed hooks. ([#1966](j178/prek#1966)) - `language_version` no longer accepts direct executable paths. Use `language_version: system` for a system toolchain, or use a supported version request instead. This path form did not work reliably before, so existing working configs should be unaffected. ([#1831](j178/prek#1831)) ##### Enhancements - Expand tilde in `--config`, `--cd`, `--log-file` and `--git-dir` ([#2063](j178/prek#2063)) - Prevent auto-update cooldown downgrades ([#2055](j178/prek#2055)) - Use managed npm cache for node hooks ([#2075](j178/prek#2075)) ##### Bug fixes - Fix npm config env overrides for node hooks ([#2074](j178/prek#2074)) ##### Documentation - Add cookbook page for enabling Git 2.54 config-based global hooks ([#2061](j178/prek#2061)) ##### Contributors - [@j178](https://github.com/j178) </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.
